Turbo-BLAST and its performance

Research has shown that the performance of demapping a multilevel modulated signal can be improved by using anti-Gray mapping and iterative demapping and decoding. Iterative demapping and decoding is based on the turbo-decoding principle. In order to improve the performance of the multi-input multi-output (MIMO) Bell-Labs Layered Space Time (BLAST) wireless communication algorithm, the combination of BLAST and iterative decoding is examined. This principle is called turbo-BLAST. Turbo-BLAST is evaluated using the extrinsic information transfer (EXIT) chart method.
